Lead delivery of Unity Engine’s C#/.NET integration, including GC, JIT, AOT, runtime libraries, and compiler toolchains. Define technical vision, improve performance and reliability, guide cross-functional development, communicate roadmaps and metrics, support users, and mentor team members. The role requires deep C# and C++ expertise, compiler knowledge, hardware architecture understanding, and proprietary game engine development experience.

Build and maintain large-scale machine learning infrastructure, including training-data pipelines, distributed model-training workflows, and orchestrated ML pipelines. Improve dataset validation, monitoring, testing, reproducibility, and system performance while partnering with ML engineers and researchers to translate research ideas into reliable production systems.

Build and operate Unity’s machine learning infrastructure, including data and feature pipelines, distributed training workflows, orchestration, model serving, monitoring, validation, and testing. The role involves delivering ML platform projects end-to-end, troubleshooting complex pipeline issues, improving reliability and reproducibility, and collaborating with ML engineers, researchers, managers, and partner teams.

Design, develop, deploy, and operate distributed backend systems supporting large-scale, low-latency online model inference. The role owns inference platform technical direction, scalability, reliability, observability, and cloud infrastructure on GCP and Kubernetes. Responsibilities include partnering with ML engineers, optimizing high-throughput services, implementing DevOps and SRE practices, and monitoring production systems with Prometheus and Grafana.

Build and operate large-scale machine learning systems for ads personalization, including ad ranking, conversion-rate prediction, recommendation, behavioral modeling, and bidding optimization. Monitor model quality, calibrate predictions, address data drift and delayed feedback, and guide technical direction and project execution. The role requires collaboration with engineering leads and communication of complex technical concepts to non-engineering stakeholders.

Prepare quarterly and annual ASC 740 income tax provisions, U.S. federal and multistate tax compliance workpapers, R&D tax credit analyses, tax disclosures, cash-tax forecasts, and SOX controls. Coordinate with external tax advisors, auditors, and internal accounting and finance teams. Improve tax processes, reconciliations, controls, and data workflows using Excel, OneSource Tax Provision, and automation tools.

Principal Product Manager leading the strategy, roadmap, and evolution of Unity LevelPlay’s mobile advertising mediation platform. The role owns platform decisions across auctions, bidding, network integrations, monetization, analytics, and publisher tooling. Responsibilities include partnering with engineering, data science, design, publishers, and ad networks; driving revenue-impacting decisions; aligning stakeholders; shipping scalable products; and mentoring other product managers. Deep ad tech, marketplace, mobile gaming, experimentation, and machine learning experience is expected.

Design, build, and operate large-scale online ML inference infrastructure to serve production models with low latency and high reliability. Optimize inference performance, enable distributed training workflows, integrate ML pipelines with orchestration systems, improve observability, and support safe model rollout, canary testing, and automated rollback. Lead architectural improvements and collaborate with ML engineers and product teams to scale, monitor, and streamline model deployment and iteration.

Lead advanced data science for Unity’s advertising business, analyzing revenue, supply, demand, and customer behavior. Define metrics, evaluate ML and product initiatives, guide roadmaps, and turn large-scale data into executive-level recommendations. Partner with Product, Engineering, Sales, and Finance, while mentoring data scientists and providing technical leadership without formal management authority.

Lead the architecture and development of Unity Ads’ iOS SDK. Design high-performance Swift components, ensure backward compatibility, collaborate with Android engineers, and own complex initiatives from design through rollout. Diagnose production issues involving lifecycle, concurrency, memory, networking, rendering, WebViews, and host-app integrations. Improve performance, reliability, crash rates, observability, and release safety while mentoring engineers and influencing technical direction.
